MOREThe Westlake University team has developed a new optical fiber spring sensor with a detection limit of picobarn, which may be used to discover microscopic physical phenomena.
Spring scale is a macroscopic force meter, which is often used to weigh various fruits, vegetables, and commodities. If the size is reduced to the micro-nano scale, is it possible to calibrate and "weigh" tiny forces like a spring scale?This requires a significant reduction in the detection limit of the sensor, placing extremely high demands on the precision of the device. In previous studies, ...
